Application fi1ed October 7, 1910. Serial No. 585,831.

To all whom it may concern:

Be it known that I, ALFRED C. CLAYTON, of the city of Toronto, in theProvince of Ontario, Canada, have invented certain new and usefulImprovements in Water-Heaters, of which the following is aspecification.

This invention relates particularly to water heaters using gas as a fueland intended for attachment to kitchen range boilers, and my object isto devise a simple and cheap heater which will be economical in gasconsumption. I attain my object principally by circulating the waterthrough water sections spaced apart, connected by a pipe and connectedeach with an integral flaring skirt of solid metal. The skirts tend toconcentrate the hot products of combustion on the undersides ofthe-sections, but are preferably notched to admit of a certain amount ofair normally passing up outside the sections mingling with the productsof combustion below the sections. The lowermost section at least haspassages formed through it for the products of combustion which areconcentrated against the pipe connecting the bottom section with thatabove it by a frusto-conical funnel.

Figure l is a vertical section of a heater constructed in accordancewith my invention. Fig. 2 is a cross-section on the line a...a,Fig. 1.

In the drawings like letters of reference indicate corresponding partsin the different figures.

A is the casing formed as usual of sheet metal provided with a castmetal top 13 and base ring C.

D is the gas burner preferably of annular form and supported on the lugE formed on the base ring G.

The water containing system of the heater comprises a plurality of watersections. The lower section F is provided with one or more outer inletsG preferably at opposite sides whereby the heater is made right or lefthanded. The inlet nut required for use will be closed by a plug P whichis indicated at the right hand side of Fig. 1. This section F has anannular opening H therein for the products of combustion. Above thesection F is located the section I having a series of openings J formedtherein for the passage of the products of combustion. The two watersections are connected by the pipe K and from the upper section extendsthe outflow pipe L leading to the range boiler.

This outflow pipe preferably leads out through the outlet M for theproducts of combustion. A smoke pipe may be connected with this outletif desired.

Surrounding the pipe K is a frusto-conical funnel Q which rests on thelower section F and receives the products of combustion passing throughthe opening H. The upper end of the funnel is located a short distancebelow the under side of the upper section I. This funnel concentratesthe hot gases against the pipe K and delivers them centrally against theunder side of the upper section I. An important feature of my inventionlies in the provision of one or more of the water sections with aflaring skirt N. These skirts are preferably integral with the sectionsand extend toward the inner surface of the casing A, but leave a clearspace by which air may pass. These skirts keep the products ofcombustion traveling through the sections, instead of passing around thesame in contact with the casing. At the same time air may pass up freelyaround the inside of the casing keeping the latter cool and providingadditional air to render the combustion of gas as perfect as possible.To aid this air in mingling with the products of combustion notches Oare formed in .the skirts N. These notches in adjoining sectionspreferably break joint, as indicated in Fig. 2, though in Fig. 1 forconvenience of illustration they are shown in line with one another.

It will be noted that the water space in the sections does not extendinto the skirts N, so that perfect drainage of the sections is obtainedfrom the inlets G whenever necessary.

I find that a construction such as described will satisfactorilyaccomplish the objects of my invention, the gas consumption for theamount of hot water obtained being very low.

What I claim as my invention is 1. In a water heater the combination ofa water section provided with a water inlet, a water outlet and apassage for the products of combustion; an integral skirt of solid metalformed on said section; and a surrounding casing separated by a smallspace from said section and skirt.

2. In a water heater the combination of a water section provided with awater inlet, a water outlet and a passage for the products ofcombustion; an integral skirt of solid metal formed on said section; anda surrounding casing separated by a small space from said section andskirt, openings being formed through said skirt to permit of air passingup outside the skirt mingling with products of combustion under thesection.

3. In a water heater the combination of a water section provided with awater inlet, a water outlet and a passage for the products ofcombustion; a second section above the first provided with a water inletand a water outlet; a pipe connecting the water outlet of the lowersection with the inlet of the upper section; and a funnel surroundingsaid pipe adapted to concentrate the products of combustion passingthrough the lower section against the said pipe and the central part ofthe underside of the upper section.

4. In a water heater the combination of a water section provided with awater inlet, a water outlet and a passage for the products ofcombustion; a second section above the first provided with a water inletand a water outlet; a pipe connecting the water outlet of the lowersection with the inlet of the upper section; a funnel surrounding saidpipe adapted to concentrate the products of combustion passing throughthe lower section against the said pipe and the central part of theunderside of the upper section; a surrounding casing; and a skirt oneach section extending toward but separated from the casing by a space.

5. In a water heater the combination of a water section provided with awater inlet, a

water outlet and a passage for the products of combustion; a secondsection above the first provided with a water inlet and a water outlet;a pipe connecting the water outlet of the lower section with the inletof the upper section; a funnel surrounding said pipe being formedthrough said skirt to permit of air passing up outside the skirtmingling with products of combustion under the section.
